Home & Business is limited to 5 electronic filings. If I buy 2 copies, can I file up to 10 returns electronically from one computer?

NO

 

Turbo Tax still has a Free Edition for very simple returns. But they are no longer participating in the IRS Free File website.

NO.  The limit of five federal e-files is not a TurboTax limit.  It is an

IRS

limit.  The IRS will not let you use do-it-yourself software to e-file more than five federal returns from your computer.  If you need to prepare more than five for family members, etc., the additional ones can be filed by mail.
